Python没有显示错误代码，但没有输出

Question

我是编码的新手，所以我希望这是一个小错误。以下是一份关于运纸员工资的作业代码。我没有得到错误代码，但没有输出，甚至打印功能也没有显示。请帮助

# This program will calculate the weekly pay of a paper carrier.
# Developer: Hannah Ploeger Date: 08/30/2022
def main():
# initialize variables
paperCost = 4
commission = 0.05
# prompt user for number of papers
numPaper = eval(input("How many papers are delivered on your route?"))
# prompt user for days of delivery
numDays = eval(input("How many days was the paper delivered this week"))
# prompt user for tips recieved
numTips = input("How much did you recieve in tips this week?")
# calculate salary
weekPay = ((numPaper * numDays) * paperCost) * commission
totalPay = weekPay + numTips
# display output
print("This week you delivered", numPaper, "papers")
print("Your salary this week is $", weekPay)
print("Your total tips were $", numTips)
print("Your total pay is $", totalPay)

Answer 1

添加以下内容：

if __name__ == "__main__":
main()

Answer 2

只需调用主函数

def main():
# initialize variables
paperCost = 4
commission = 0.05
# prompt user for number of papers
numPaper = eval(input("How many papers are delivered on your route?"))
# prompt user for days of delivery
numDays = eval(input("How many days was the paper delivered this week"))
# prompt user for tips recieved
numTips = input("How much did you recieve in tips this week?")
# calculate salary
weekPay = ((numPaper * numDays) * paperCost) * commission
totalPay = weekPay + numTips
# display output
print("This week you delivered", numPaper, "papers")
print("Your salary this week is $", weekPay)
print("Your total tips were $", numTips)
print("Your total pay is $", totalPay)
main() # calling main function
